I didn’t know that there were so many! I realize that there are still more than the ones I have listed here. To be honest, I got tired of searching for them. If you know of any that you think are really good that I missed, or if you find any broken links, please let me know. Here is the criteria that I used for this list: I only included rules that are available as a free PDF file. I didn’t include any “pay what you want” games unless they had a Suggested Price of $0.00. I didn’t include games that were not in English. I didn’t include single player games. I didn’t include some just because I didn’t like them (or they are just too different than D&D). I removed “The” from names that start with that word.These all owe their existence to Dungeons and Dragons. Most of them copy the rules of D&D at least to some extent. Some try to match the older rules as closely as possible without violating copyright laws, and others deviate quite a lot.
Where I say something like “3.5 clone”, that is to indicate that the rules are based on some version of D&D (3.5 in this example). If it doesn’t say which version I guessed. 0.0 – Original Dungeons and Dragons (OD&D) a small box set of three booklets published in 1974 0.5 – Basic Dungeons & Dragons (BD&D) 1977 1.0 – Advanced Dungeons & Dragons (AD&D) 1978 2.0 – Advanced Dungeons & Dragons 2nd Edition (AD&D2 or 2nd Ed) 1989 3.0 – Dungeons & Dragons 3rd Edition (D&D3 or 3E) 2000 3.5 – Dungeons & Dragons v.3.5 (Revised 3rd Edition or D&D3.5) 2003 4.0 – Dungeons & Dragons 4th Edition (D&D4E) 2008 5.0 – Dungeons & Dragons 5th Edition (D&D5E) 2014 OSR: “Old School Renaissance” or “Old School Revival” draws inspiration from D&D of the 1970s, I use this when the game refers to itself as OSR, or I can’t link it to a specific ruleset.

Great list! I’ll be cheking some of these, but my main OSR game is Basic Fantasy, which is a B/X retroclone, and the best at that. It’s not 3e by a long shot; check out BRFPG and see for yourself.
Cheers!
Thanks.
I downloaded and quickly glanced over each of these and I knew that I wouldn’t get everything right.
My mistake was that I was just going by what it says on page 1, “The Basic Fantasy Role-Playing Game is a rules-light game system based on the d20 SRD v3.5” But I should have looked closer – it continues “but heavily rewritten with inspiration from early role-playing game systems.”
I corrected the post.

What makes my mistake even worse – I did a comparison of Basic Fantasy and 5e here:

What is the difference between high and heavy crunch?
Low and light crunch?
Thanks!!

That is just a matter of me forgetting which term I was using.
High = Heavy and Low = Light.
Sorry of the confusion. 🙂
